This study is performed to investigate the relation between cell components and hardness which affect to the quality of dried persimmons. Moisture contents of dried persimmons were interrange of 30 to 36%. Enpung Junsi (EJ), Dungsi (Young dong) (DY) and Haman Susi (HS) had higher moisture contents than Dungsi (Sang Ju) (DS), Kojongsi (KS) and Hagakure (HK). Hardness was high in the varieties which has low moisture content such as DS, KS and HK. The significant differences of hardness and fracturability among varieties were appeared conspicuously but those of cohesiveness, adhesiveness and springiness were not appeared. Crude cell wall content, pectin and calcium content of cell wall were high in hard varieties. In the pectin fractions, water soluble pectin content was high in EJ, HS and DY but that of acid and alkali soluble pectin were high in DS, KS and HK. The cell wall of high hardness varieties observed thick and firm than that of low hardness varieties.

This study was undertaken to examine the effects of ginseng on the acceptability of kimchi for 9 days at . Kimchi was analyzed for the measurement of acidity, pH, saltiness, reducing sugar, hardness by Instron and organic acids by HPLC. Ten highly trained panelists were involved in the sensory evaluation. The data analysis revealed followings; 1. While saltiness was maintained at around 2.3% level during the entire fermentation periods, kimchi containing 2% and 4% ginseng showed higher pH, reducing sugar, hardness by Instron, and lower acidity than without ginseng. 2. Results from analysis of organic acids contained by HPLC revealed that all three groups contained relatively high concentration of oxalic acid, lactic acid and malic acid. It was also found that, as fermented progressed, the amounts of lactic acid and acetic acid increased, and those of tartaric acid and malic acid decreased while the concentration of oxalic acid did not change significantly. 3. A result of sensory evaluation revealed that kimchi containing 2% and 4% ginseng was higher in hardness, savory taste and carbonated taste, and lower in sour taste, moldy off flavor than kimchi without ginseng, thus scoring high in overall eating quality. Considering all results obtained throughout this experiments, it can be concluded that the addition of small amount of ginseng to kimchi improve overall acceptability and retard rancidity, thus increasing the period during which is eatable.

This study was conducted to establish traditional manufacturing process of Hongju, a traditional spirit by traditional Kokja and Koji method based on different materials. In the fermentation process, the changes of temperature, pH, total acid, alcohol, total sugar and microflora in mash were analyzed. During the whole fermentation period, the temperature in mash made by Kokja method was reached to , and that of Koji method was reached . There was no significant difference in pH by different treatments and the initial pH in Koji method was pH 6.0 and the final pH was 4.0. The content of total acid was higher in mash processed by Kokja method than that of Koji method. Alcohol content was higher in mash processed by Koji method. The content of total sugar in all samples were reduced gradually according to progress of fermentation. Yeast populations in all samples were increased up to 6 days of fermentation and then decreased gradually. Lactic acid bacteria were increased until 3 days of fermentation and then decreased until the fermentation completed.

The flavor and organoleptic properties of Hongju prepared by Kokja and Koji method were tested. There was no great difference of total acid in Hongju with different fermentation methods. The alcohol content of Hongju prepared by Koji method was higher than that of Kokja method and methanol content was very little as about mg/ml in all samples. The aldehyde content was mg% and fusel oil was higher in Hongju prepared by Koji method than that of Kokja method. As the result of sensory evaluation, new Hongju, S-N prepared by Kokja method with wheat and rice was to be best quality.

A study on the foods of annual custom in Cheongju area was done to know the present practices and compare with Dongkooksesiki (동국세시기(東國歲時記)), Youlyangsesiki (열양세시기(洌陽歲時記)), Kyoungdojabji (경도잡지(京都雜誌)), and the results of a study on the gala foods in Kangweon province. Those annual custom which are celebrated in Cheongju area are Seolnal (New Year's Day) (100%), Chuseok (Harvest Moon Day) (100%), Daeboreum (the 15th of January) (92.6%), Dongji (the winter solstice) (75.2%), and Sambok (the period of summer heat) (67.4%) in the order of higher percentages. No subjects for this survey are keeping on celebrating Junghwa (servants day), Jungwon (the 15th day of the 7th lunar month), and Nabpyoung. Foods of annual custom on Chuseok and Seolnal had a greater variety, compared with those enjoyed on other annual custom. Foods of annual custom such as Ddugguk, Mandoo on Seolnal, Ogokbab, Mugeunnamul, and Buryum on Daeboreum, Songpyun on Chuseok, Patjuk on Dongji were being enjoyed by most people. But the other foods of annual custom are enjoyed in a lower percentage or almost forgotten.

Kasugadaisha was built in the 9th century at Nara, Japan and it was the powerful Fujiwara's Shrine at that time. And also Wakamiyasai which has transmitted from generation to generation about for 1200 years at Kasugadaisha is typical sacrificial service of Nara Ages and it was built up with the historical background from Korean peninsula, especially Bekje. So it could be presumed to be important data to survey the sacrificial service in order to study on the ancient dietary culture of Korean and Japanese. 1) They used a live flower or paper flower in every sacrificial services. But in Korea, it has been used not only in the sacrificial services but also in happy events. And also it has been changed to use silk or developed rice cake instead of paper. 2) Steamed rice cake in Siru has been taken after boiled rice and unpolished rice. 3) Fried rice cake like doughnut was beginning of fried cake like Yak-kwa. 4) Four colors of red, yellow, green and white are symbolic at the high offering. There are a lot of cake, candy and some kind of biskuit four colors used in every events even now in Korea.

The purpose of this study were to investigate opinions on the contents and method of the educational public information of food sanitation, to enrich education of food sanitation for consumer. Data of questionnaires were collected from 78 consumer protection association and 66 food industrial company. The results of the study were summarized as follows; The educational public contents of food sanitation appropriated is remarked as a basic knowledge in a safety of food (an additive, an agricultural medicines) and in nutrition and sanitation. The effective method of public information is suggested as a TV, Radio, utilization of periodicals and pamphlet. The crucial problem of the imported food surveyed in the consumer protection association is an agricultural medicines and a heavy metal. In the food industrial company, it is remarked that the problem occurs in deposit and storage of food from the standpoint of sanitation. Finally, improvement of sanitary condition in food selling place is suggested.
